如何静态链接使用crypto / tls的Go二进制文件?

If you try to compile the following Go program:

package main

import _ "crypto/tls"

func main() {

}

You'll wind up with a dynamically linked Go binary. This is annoying for me (I'm building a Go binary inside a Docker container, which uses a different libc from my host, which will result in the binary not running on my host).

How does one force Go to build such a program statically?

如果您尝试编译以下Go程序:

  包main 
 
import _“ crypto / tls” 
 
func main(){
 
} 
   
 
 

链接Go二进制文件。 这对我来说很烦(我正在Docker容器中构建Go二进制文件,该容器使用与主机不同的libc,这将导致该二进制文件不在主机上运行。)

如何强制去静态地构建这样的程序?

    The only OS where crypto/tls uses cgo is darwin, where it needs to call FetchPEMRootsto get the root CAs.

    The reason your program is using cgo is because crypto/tls imports the net package, which links to the host resolver by default. You can build the net package without cgo using the "netgo" build tag.

    go build -tags netgo
    

    Or if you're on a release where the std lib packages won't be built by default, you can trigger them to be compiled with a new installsuffix

    go build -installsuffix netgo -tags netgo
    

    Since you're not going to have the need or ability to use cgo in your environment, you may want to just build everything with CGO_ENABLED=0 to disable cgo entirely.
